💅 NAME 💅

okay so bestie, this is w1_f23_write — it Writes to the scratchpad and reads it back for verification. no cap, that's literally what it does. 🎀

---

✨ SYNOPSIS ✨

int w1_f23_write (struct w1_slave *sl , int addr , int len , const u8 *data );

---

🦋 ARGUMENTS 🦋

• sl — The slave structure. yes bestie, it's giving "the main character struct" energy. 🫶
• addr — Address for the write. where we're putting the vibes, basically. 📍
• len — length must be <= (W1_PAGE_SIZE - (addr & W1_PAGE_MASK)) ⚠️ like, literally read that twice. it's a hard limit, not a gentle suggestion. no cap.
• data — The data to write. the actual content, the moment, the whole point. 💖

---

🌸 DESCRIPTION 🌸

Then copies the scratchpad to EEPROM. 🧚

The data must be on one page. 🍓 The master must be locked. 🔒

okay so real talk: those two rules aren't optional, bestie. one page only, and lock the master. this is not a drill. 😭

⭐ RETURN ⭐

• 0 = Success 👑 (slay)
• -1 = failure 💀 (not slay, try again)
